IMPROVEMENT IN COTTON-CULTIVATQRS.

Specification forming part of Letters Patent No. 011,077, dated March 22, 1870.

10 all whom it may concern Be it known that I, \V. J. ANDREws, of Columbia, in the county of Maury and State of Tennessee, have invented certain new and useful Improvements in Cotton-Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ing, and to the letters of reference marked thereon, which forms a part of this specification.

- deemed it necessary to represent in the draw- Up 011 the center of the front side of the frame A are placed two cars, a a, between and in which a box or collar, 0, is pivoted, saidbox being provided with journals which pass through the cars a a. The box 0 forms the front bearing for a shaft, D,which passes above the frame A toward the rear and through {1.11- other box or collar, E. This latter box is pivoted within a circular or oblong enlargement on a screw-rod, G, which passes through the rear side of the frame A at the center, and also through aguide, H, attached to the frame for that purpose. A screw-crank, I, is placed on the rod G above the guide H, resting on the same, so that by turning said crank the screw-rod can be raised or lowered at will, thus raising or lowering the rear end of the shaft D, the swinging box or bearing 0 at the front end adjusting itself to the changed position of the shaft.

Upon the rear end of the shaft D is secured a polygonal-shaped wheel, J, having a series of hoes, K K, secured to its sides, as shown in the drawing. The hoes KK are made adjustable upon the circumference of the wheel J, so as to throw the earth, when the wheel revolves, in any manner desired by the operator.

The wheel J, with its hoes, is revolved in the following manner: Upon the axle B is secured a miter-wheel, L,which gears with a pin ion, 1), on the end of a small shaft placed in suitable bearings under the front part of the frame A. A pulley, d, on the front end of said shaft is by a cord or belt," 0, connected with a pulley, f, upon the front end of the shaft D, so that when the machine is in motion the shaft D, with its wheel and hoes, will be constantly revolved. By means of the screw-crank I the depth at which the hoes are to work is easily regulated, and by the same means they are entirely lifted out of the ground when so desired.

Under the center of the front end of the frame A are hinged two bars, which, with another connecting-bar at their rear ends, form a triangular frame, M, to which the scrapers N N and harrows 0 O are secured. This frame M is held at its. rear end by means of a loose collar, h, on the shaft D,whioh collar has j ournals or pins passed into two upright bars, 7c 7.", attached to the frame M, so that when the shaft D is raised or lowered the said frame, with the the scrapers and harrows, is also raised and lowered. The upright bars 7t 70 also move a little from side to side on the journals of the collar h, so as to allow the frame M to swing somewhat from side to side Whennecessary.

On the axle B is placed a collar or loop, 121, from which extends a forked bar, 1?, toward the rear, the end of which bar surrounds the frame M, between the uprights 7t 7;. Alever, R, extends forward from said collar m, so that the operator, seated upon his seat at S, can by pressing his foot on the lever B raise the T frame M and shaft D. This lever is then held in any position set by the operator by means of the toothed bar T.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of screw-rod G with rocking box E and shaft D, all operating substantially as an d for the purpose set forth.

2. The auxiliary frame M,attached to main frame A, and arranged to operate substantially as and for the purpose described.

3. The auxiliary frame M, provided with scrapers N N and teeth 0 0, arranged to 0p my own I affix my signature in presence of erate as and for the purpose specified. two witnesses.

4. The combination of shaft A screw-rod G boxes 0 E, wheel J, with its adjustable hoes: ANDREW frame A, and auxiliary frame M, all arranged Vitnesses: substantially as set forth. L. H. ATTWELL,

' In testimony that I claim the foregoing as W. S. MoGREeon.
